Abstract
The invention relates to a compacted and densified metal material having one or more phases formed of an agglomerate of grains, the cohesion of the material being provided by bridges formed between grains, said material having a relative density higher than or equal to 95% and preferably higher than or equal to 98%.
Claims24
A compacted and densified solid metallic material comprising one or more phases formed of an agglomerate of metallic powder grains, wherein:
- cohesion of the densified solid metallic material is provided by metallic bridges formed through direct surface bonds between the metallic powder grains,
- said densified solid metallic material has a relative density greater than or equal to 95%, and
- an external surface of each of the metallic powder grains in the densified solid metallic material has an irregular random shape comprising hollows and peaks.
A component comprising a compacted and densified solid metallic material comprising one or more phases formed of an agglomerate of uncoated metallic powder grains, wherein:
- cohesion of the densified solid metallic material is provided by metallic bridges formed through direct surface bonds between the metallic powder grains,
- said densified solid metallic material has a relative density greater than or equal to 95%, and
- an external surface of each of the metallic powder grains in the solid metallic material has an irregular random shape comprising hollows and peaks.
